Auto focus dosen't work

You are sure on both, the camera and the lens, AF is selected?
If you did and the lens does not work, please try anther lens, to find out, if it is a malfunction of the lens or of the camera.
You also could check if all contacts on the lens and in the camera are clean and not corroded. If the are not clean and shining, please use a dry cloth to carefully rub the contacts clean. Be careful not to bend any contact in that process. please be careful not to leave any dust n the camera or lens. Use the lens and camera caps when you are not cleaning one of them.

Busy and or Error 01

For error message 01 the manual says: Communications between the camera and lens is faulty. Clean lens contacts.
Solve: Clean the electrical contacts on the camera and lens and use a Canon lens.
SO if you are using a different lens or a non Canon lens this could be what is wrong.

If you never changed a lens, it still can be that something went wrong in the communication between the camera and lens. Just careful remove the lens and with a dry and lint free cloth, clean all contacts on the lens and in the camera. While working on the lens, close the camera with the camera cap, or put the camera face down.
Don't use anything sharp while working on a lens or a camera.

Try cleaning the electrical contacts on the back of the lens and in the lens mount on the camera body.

Do you have another lens and/or camera body you can try? Does this lens work on another body, or does another lens work on this body?

I use this lense with a Canon rebel and get an error message that it cannot communicate and to clean contacts. How do I do that?

Wow, I'm surprised to actually tells you to clean the contacts? What model Canon Rebel do you have? Okay for cleaning the contacts simplest and most effective way is with a good clean new red rubber pencil eraser. Make sure the camera is off and remove the lens, place the camera body face down on a clean lint free surface or install a body cap if you have one. Hold the lens as vertical as possible but tilted slightly to be able to see and work with the gold contacts. Lightly rub the contact surface with the eraser, it won't look as if you have done much but it does shine them up well. When you have finished cleaning them use a lens cloth (not a tissue) to lightly clean any rubber dust from around the contacts and the rest of the mount. There shouldn't be much if any you are polishing the surface not erasing. Set the lens aside and while holding the camera as much as possible lens side down take the eraser and gently clean the contacts again it doesn't take much don't forget you are polishing not erasing, a few passes should be all it takes. Once done again use the lens cloth not a tissue and clean the area of any dust that may have occurred. Assemble the lens and camera and turn it on.

On another note but a related subject. How new is your Rebel compared to the Quantaray lens? If the lens is newer then the camera that's fine but if the camera is newer then the lens this also may be part of the problem.

Error 99 on canon 300d

Canon's error 99 is a catch all for several things the short answer is an electronic connection. Something isn't making contact and the first place to go is to the "gold" contacts between the lens and the camera body. Make sure the camera is off and remove the lens, place the camera lens side down on a clean dust/lint free surface or put a body cap on. Take the lens and holding as vertical as possible with the gold contact points down use a soft rubber red pencil eraser to lightly clean the contacts. You can remove any rubber dust and partials with a lens cleaning cloth NOT TISSUE. Make sure the area is clean of lint and dust, place the rear lens cap on or stand the lens up on a clean dust and lint free surface. the camera is a bit more tricky as you need to clean the contacts inside the mirror box. Hold the camera as best you can face down and again use the pencil eraser to lightly clean the contacts. Holding the camera as mus as possible lens side down. This will minimize any dust, dirt or lint getting into the camera body and eventually ending up on the sensor. Remove any rubber dust with a lens cloth not tissue and don't use any liquid, don't use a puffer either all that will do is drive dust partials into the camera. Once that's done install the lens, next remove the battery and do the same cleaning trick with the battery contacts, if you have a battery grip do the same thing. Okay now check out the camera if everything is go and works then you are good to go. If not then I would suggest doing a camera firmware update, all updates can be found on the Canon web site they are free and will correct any issues your camera has with the internal programming which may also be the cause of your error 99.

My lens locked suddenly Canon EF-S 17-85mm f/4-5.6 IS USM Lens on a 20D body

Possible power problem make sure the camera has sufficient battery power and is functioning as it should (less the lens) if this is okay then the problem is between the lens and body gold contacts. It's a quick and easy repair you can do yourself. Shut the camera off remove the lens and put the body cap on the camera if you don't have a body cap place the camera on a clean lint free surface like a glass table or counter top. Use a new clean red pencil eraser to gently rub the gold contacts on the lens. Hold the lens as vertical as possible when you are doing this to minimize the rubber dust getting into the rear lens element. Clean the area of rubber dust with a puffer blower or lens cloth not a tissue. Set the lens down on the clean lint free surface and gently clean the gold contacts in the camera body keeping the camera lens mount down to minimize any rubber dust from getting into the sensor area. Clean the contacts with a lens cloth only do not use a blower/puffer, re-install the lens and it should come on. When installing the lens make sure it makes a solid click and locks securely in place.

Canon err 01

This error means "Communication between the camera and lens is faulty. Clean the lens contacts." If you are using the same lens on both cameras, the problem is with the metal contacts on the rear of the lens where it communicates with the camera body. You can gently clean these contacts by using a clean pencil eraser. Make sure you hold the lens "bottom down" as you clean it so that the eraser debris falls to the table instead of inside the lens!
